In writing this HTML, please note how I show the less than and the greater then symbols - go into the source code to see this.
This code is used because the less than and greater than symbols have special meaning to XHTML and HTML so showing them as text can become problematic. Other special symbols also have their on codes - I have only used a few here.

Remember, adding emphasis to your page can be done using the <em> tag.
I want these words to stand out from the rest.

There is a third kind of list (we have looked at ordered and unordered) which is called a definition list. This list uses the <dl> tag which stands for definition list. Within this list you can define the term you are using with the <dt> tag and the definition with the <dd> tag. For example:

Extensible Hypertext Markup Language
Hypertext Markup Language
Cascading Style Sheets
